Title: Improvements in or relating to method and apparatus for manufacturing tubular glass articles
IPC: C03B23/09
Filed: 1933-03-20
Abstract: 402,306. Glass manufacture. HOFMANN & Co., A., 635, 15th Street, West New York, New Jersey, U.S.A.-(Assignees of Hofmann, A.; 10, Clermont Avenue, Palisade, and Anderson, V. ; 437, Greenmont Avenue, Cliffside Park, both in New Jersey, U.S.A.) March 20, 1933, No. 8421. Convention date, May 12, 1932. [Class 56.] A machine for producing short sections of flared glass tubing, particularly the " flares " used in the construction of electric lamp bulbs, comprises a device for holding and rotating a glass tube, means for feeding the tube periodically downwards through the holder, means for heating and shaping the lower end of the tube, means for cutting-off a length of the tube, and a mandrel which is inserted in the tube to preserve its diameter and to act as an abutment during severing. The operation of the device is illustrated by Figs. 10- 14. A glass tube X, Fig. 11, is held in a vertical position by a rotating chuck A, and a vertically movable sleeve B, which is coaxial with the chuck A and rotates in unison with it, is raised into contact with the lower end of the glass tube. A mandrel C, which slides within the sleeve B, enters the bore of the tube. Next, the sleeve B descends and the glass tube follows it by gravity to the position shown in Fig. 12. The chuck again closes and rotates the tube, while the flame from a burner G heats and softens the lower end of the tube. When the glass has become soft, the sleeve B and the mandrel C descend still further to the position shown in Fig. 13. A flaring-device D is now moved into the glass tube and shapes the softened lower end. The gas flame is then turned off, the flaring-device D is removed, and the sleeve is raised again into contact with the flared end of the tube, as shown in Fig. 14. The mandrel C, however, continues to rise within the tube in order to serve as an abutment for a cutting- device E. A burner H softens the glass along the line of the cut, the disc E is pressed against the softened glass, and the cut end of the severed section of the tube is smoothed by the flame of the burner H. Finally, the mandrel C is lowered, and a knock-off bar F, Fig. 10, swings forward and removes the flared tube Y from the machine. The machine, which is shown in side elevation in Fig. 3, comprises two sets of operating devices for shaping two tubes simultaneously. The chucks are housed in casings 42 supported by a standard 40 above a table 28, and a driving shaft 30 and a cam shaft 20 are supported below the table. The cams on the shaft 20 impart the necessary movements to the different elements of the machine.

Title: Improvements relating to apparatus for playing a table game
IPC: A63F7/02
Filed: 1939-03-16
Abstract: 526,459. Table games. PERKS, G. E. R. March 16, 1939, No. 8493. [Class 132 (ii)] A game apparatus of the " pin table" type wherein the balls enter traps 3, Fig. 1, in the surface of the table and thereby automatically illuminate corresponding signals 4 is characterized by the provision of selective means, e.g., a bank of press buttons 29 for releasing one or more of the balls contained in the traps and breaking the corresponding signal circuit or circuits, to permit of the replay of the released ball or balls. In commencing a game the balls may be liberated from the traps 3 for play, by operating the usual coin slide 7 and after elevating the balls in usual manner by a mechanism 8 they may be projected by a plunger 10 one by one up a channel 9 on to a raised board 33a whence they run into the traps 3 or to the bottom of the table. As each ball passes over the board 33a it depresses a counting contact 33, Fig. 3, and energizes a magnet 36. The magnet advances the contact arm 35 of a switch 34 until, when all the balls have been projected the contact arm engages a contact 37 thereby permitting the buttons 29, resting on contacts 31, to become effective when operated. The presence of a ball in a trap 3 depresses a pivoted ballsupporting plate 11, Fig. 4, and closes the contacts 18, 19, 20 of a jack 21 thereby illuminating the corresponding lamp 6. The plate 11 rests on the armature 15 of a magnet 17. When all the balls have entered traps, that is when the contact arm 35 has engaged the contact 37, a lamp 39 advises the player of this fact and the player, if he desires to replay any one or more of the balls in the traps, depresses the corresponding buttons 29 thereby energizing, through the contacts 31, corresponding magnets 17 and liberating the plates 11 to return the selected balls for replay. Balls that fail to enter a trap run to the bottom of the table and depress an electric contact. causing the plunger of a magnet to project the ball up the table. When a rejected ball has been replayed, it passes over the counting contact 33 and moves the contact arm 35 thus preventing further rejection on balls. A time switch may be incorporated to put a definite limit upon the playing time. In a modification, the counting contact 33 and raised board 33a are dispensed with and the magnet 36 is energized, to actuate the contact arm 35, by means of a ball-actuated contact strip located in front of the ball elevator.

Title: Improvements in or relating to processes and apparatus for the production of aluminium and of mixtures of aluminium and aluminium carbide
IPC: C22C1/02
Filed: 1959-03-13
Abstract: <PICT:0893345/III/1> In a continuous process as in Specification 865,861 for the production of a mixture of aluminium and aluminium carbide by the reduction of alumina with carbon at a temperature of 2300 DEG -2600 DEG C. in an electric arc furnace, the molten mixture is intermittently tapped from the furnace.  Thus in the furnace shown in Fig. 1, the molten aluminium-aluminium carbide mixture is periodically tapped from the furnace hearth 1 by piercing the crucible wall with an auxiliary electrode 9 and is allowed to run into a subcrucible 2 arranged within the heat insulating material surrounding the furnace.  The mixture is allowed to cool slowly and solidify in the subcrucible and is removed through a door 10. The weight ratio of carbon to alumina in the charge supplied to the furnace is 0,43\sB10%.  The carbon of the charge may be in the form of charcoal, crude or baked petroleum coke, purified powdered coal or coke, sawdust or carbohydrate.  The alumina may be prepared by a carbothermal reduction of aluminium ore with excess carbon at 2100 DEG  C., the pure alumina then being tapped, communicated by an air stream and solidified into hollow spherical particles.  Aluminium may be separated from the product mixture by distillation or preferably by treatment of the mixture with a flux, e.g. at least one halide of an alkali metal or alkaline earth metal or aluminium.  The slag is removed from the aluminium and washed with water to recover the aluminium carbide which may be added to fresh charge for the furnace. Boron may be added to the furnace charge as borax, boric acid, boron carbide or boracite to prevent titanium contamination of the pruduct aluminium.

Abstract: 654,476. Automatic tension control systems. IGRANIC ELECTRIC CO., Ltd. April 1, 1948, No. 9238. Convention date, April 12 1947. [Class 38 (iv)] [Also in Group XXXVII] In a wire drawing machine the tension is automatically maintained constant by the control of the voltage applied to the driving motor. The field of the generator supplying the motor is regulated, through a thermionic device, by an inductance which varies in accordance with wire tension ; control signals corresponding to the rate of change of tension, rate of change of generator voltage, and magnitude and sense of generator current are also employed. As shown, the driving motor M is supplied by generator G, the field 20 of which is energized from source 31 through the thyratrons 33, 34, to the grids of which are applied the control signals which comprise D.C. voltages developed at L, M through valves 48-51, 64, 68. Changes in wire tension produce corresponding alterations in the inductance 27 which effect phase changes on the grids of thyratrons 59, 60, the output currents of which develop a D.C. voltage in resistor 62 which regulates valve 64. An increase in generator current causes a rise of voltage across resistor 39 which opposes the adjustable bias voltage at 43 so as to reduce current through valve 48 and cause 50 to conduct thus lowering the voltage of N and reducing the generator field excitation. Upon a sudden decrease of motor load the voltages at shunt 38 and potentiometer 41 similarly operate upon valve 51 to correctively adjust the bias of 33, 34. To prevent hunting, the differentiating circuit 63, 67 and condenser 72 are provided ; the latter causes bias adjustment of valves 33, 34 through valve 68 in accordance with rapid generator voltage changes.
